HBO will remember James Gandolfini on Sunday with a special tribute featuring more than two dozen friends and colleagues, including "The Sopranos" family creator David Chase, his "Sopranos" wife Edie Falco, and "Sopranos" underboss Tony Sirico.

Gandolfini died of a heart attack on June 19 while vacationing in Italy with his son. After "The Sopranos" went off the air, the actor maintained a fruitful relationship with the network that made him an international star. He produced two documentaries on veterans' issues for HBO and the film "Hemingway and Gellhorn." He also starred in HBO's "Cinema Veritae," a film co-starring Diane Lane. Just before he died, he had begun working on a new mini-series "Criminal Justice."

In a promo released by HBO, Chase comments on Gandolfini's sad eyes, Falco recalls laughing with him, and Sirico calls him "a good man" who "just happened to be a brilliant, brilliant actor." Lane remembered his unexpected sex appeal.

The special includes clips of the three-time Emmy winner's work and behind-the-scenes footage. It will air on Dec. 22 at 8:30 p.m on HBO.
